This device comprises a curved plate associated views is designed for casting supported beneath a small stove and adapted babbitt linings of 3%-inches to 6 y -inches in to be run along the worn lining in order to diameter. The assembly includes a semimelt and thus remove it. cylindrical mandrel 1 mounted on a base The invention is fully disclosed in the tolv plate 2. The bottom edge. of the mandrel lowing description and in the accompanying is formed with a diametrical rib 3 from drawings in which; 7 which extends a perpendicular slotted arm Figure 1 is a perspective view of one of et radially to the curved wall. The lower the mandrels; surface of the bottom plate has a flange Figure 2 is another perspective view 5 from the midpoint in which extend a pair thereof taken from the rearside; of arms 6 to the op )osite corners and an Figure 3 is a plan view thereof; arm 7 to the midpoint of the opposite side. Figure 4 is a perspective view of one of The flange 5 has a pair of alined spaced slots 8, and the intersection 9 of the arms 6 and 7 is formed with a slot 10. A bolt and nut device 11 passed through the slotted arm 4c and into the slot 10 holds the mandrel and base plate together. The edges of the mandrel 1 have inwardly extending flanges 12 to which are secured a pair of back plates 13 by means of bolts and nuts 14. The lower edges of the plates have slots 15 through which are passed bolts 16 extending into the slots 8 whereby the back plates are further secured to the base plate.

In the use of this form of device, the bearing 17 to be lined is based upon the base plate so that a space corresponding to the thickness of the desired lining is retained between the mandrel and the bearing; In this position the flanges 18 of the bearing engage the back plates 13 as illustrated in Figure 7. A liner or clamp plate 19 is now placed over the bearing so that the flanges 20 of the clamp plate engage the flanges 18 of the bearing. Clamps 21- are now applied to engage the flanges 20 and back plates 13, whereby the bearing is secured in proper position. The Babbit metal 22 is now poured into the space between the mandrel and the bearing, and allowed to harden before the mould is dismantled. The liner 19 is formed with a vertical slot 23 to accommodate the rib 17 on the back of the bearing if the bearing has such a rib.

In casting linings of the same radius of curvature as that for which the described embodiment is adapted, but of less angular magnitude, the assembly shown in Figure 10 is employed. The bearing flanges 18 are necessarily spaced from the back plates 13, and in order to maintain this spacing, supplemental liner plates 2a are placed against the inner faces of the flanges and also against the outer wall of the mandrel to close the casting space. The plates 21 carry screws 25 which project through appropriate apertures 26 in the back plates 13. The plates 24 are held at the proper distance from the plates 13 by means of clamp nuts 27 threaded on the screws and bearing against the plates 13. Clamps 28 are applied over the plates 24: and flanges 20 of the liner 19 in order to retain the bearing 17. The metal is poured into the spaces defined by the mandrel, bearing and plates 24; in the manner already mentioned, and the assembly is dismantled after the metal has hardened.

A modified form of apparatus for easting linings of still smaller angular magnitude but of the same radius of curvature is shown in Figure 1.3. In this construction, the liner plates 30 for defining the straight edges of the babbitt lining are adapted for connection to the back plates 13 by means of slotted fingers 31. Screws 32 are passed through the apertures 26 and through the slotted fingers 31, and are clamped to these members by means of nuts 33 to hold the parts in proper spacing. To the liner plates 30 are secured angle irons 3 1 which are so spaced as to suitably retain the bearing to be lined.

In order to cast eccentric straps, a pair of base plates 2 are connected by means of bolts 35 passed through the slots 8 01" two engaging flanges 5 and locked therein as shown in Figure 5. On the upper base of the joined plates is placed a pair of semicircular bearing yokes 3G fastened together by bolts 37. A cylindrical drum which may consist of a pair of similar sections 38 is placed within the confines oi the yokes in eccentric relation. The metal is now poured into the space between the drum and the yokes, whereby the lining is formed eccentric to the yokes.

The unit employed for bearings of a diameter from -inch to 3-inches is illustrated in Figure 6. This unit comprises a plane base plate 39 having a central aperture 10, together with a solid cylindrical drum 41 with a spindle 42'adapted,to enter the aperture. After the drum has been placed upon the plate 39, it is surrounded by the bearing, and the metal is poured into the space between the drum and bearing in the usual manner.

The embodiment shown in Figures 16 and 17 is designed for lining the bearings of '7 inch to2 -inches in diameter. This form comprises a pair of semi-cylindrical drum sections 43 and 1 1 having diametrical arms 15 and 16 respectively across their edges. Each arm 45 on the section 13 has a keyhole slot 17, and the corresponding arms 46 011 the other section 1 1, each have an aperture 48.

The parts are fastened together by bolts positioned in the apertures 48 and slidably inserted into the inner portions of the slots 47. The sections also have intermediate arms 49 which may be connected by suitable fastening devices passed through apertures 50, if the sections are open at one end.

In order to cast wide bearings, a plurality of mandrels 1 are superposed in the manner illustrated in Figures 18 and 19. For this purpose, the upper edge of each mandrel has a plurality of ears 51, and the back plates 13 have similar cars 52 at their upper edges. The members are so arranged that cars engageears and ribs 3 engage similar members on the adjacent sections. These parts are then bolted together as clearly shown in Figures 18 and 19. The remainder of the process is carried out in the manner already described.

While a specific embodiment of the invention has been illustrated and described, it is to be understood that various alterations in the details of construction may be made Without departing from the spirit of theinvention as indicated by the appended claims.

Having thus fully described the invention, What I claim as new and desire to protect by Letters Patent is:

1. Babbitting equipment comprising a curved mandrel, and liner plates adjustably connected to said mandrel.

2. Babbitting equipment comprising a curved mandrel, back plates extending outwardly from the edges of said mandrel, and liner plates adjustably attached to saidback plates.

3. Babbitting equipment comprising a curved mandrel, back plates extending outwardly from the edges of said mandrel, liner plates adjustably attached to said back plates, and means for interlocking a plurality of said mandrels in superposed position.

wardly from the edges of said mandrel,

liner plates adjustably attached to said back plates, and angle irons adapted for attach ment to said liner plates.

6. Babbitting equipment comprising a curved mandrel, back plates extending outwardly from the edges of said mandrel,

screws adjustably mounted in said back plates, and liner plates carried by said screws.

In witness whereof I have hereunto set my hand.

MAX MICHALK.
